How did Joseph Smith translate the Book of Mormon? Joseph's brief answer was "by the gift and power of God," sometimes adding that it was done by means of "Urim and Thummim."  Some have asked why Joseph Smith didn't give more specific details about the process.  In this enlightening episode, translation scholar Dr. Michael Hubbard MacKay discusses his research on the "incommensurability" of Joseph Smith's divine translation work and why it gives insight into expressions of religious truth and experience.
